RAILWAY MOTOR-CAR.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed. March 11, 1909. Serial No. 482,787.

'10 all whom it may concern:

Be it known that we, VVILLIAM S. Hovnr and MILTON H. Rrx, citizens of the United States, residing at Three Rivers, Michigan, have invented certain new and useful Improvements in Railway Motor-Cars, of which the following is a specification.

This invention relates to improvements in railway motor cars, although it is applicable for use in other forms of motor cars.

The objects of this invention are: First, to provide an improved drive connection for the engine to the traction wheels. Second, to provide in a driving connection for motor cars a clutch means in which one of the traction wheels forms one of the clutch members. Third, to provide an improved motor hand car in which the parts are very simple in structure and arrangement, so that an engine can be applied to a car of common or standard construction.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

e accomplish the objects of our invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a detail side elevation of a structure embodying the features of our in vention. Fig. 2 is a detail vertical sectional view taken on a line corresponding to line 22 of Fig. 1. Fig. 3 is a detail vertical section taken on a line corresponding to line 33 of Fig. 2, a portion of the wheel being broken away. Fig. 4: is an enlarged detail vertical section taken on a line corresponding to line 41 of Fig. 2, showing details of the shifting mechanism. Fig. 5 is a detail plan of the driving connection for the walking beam to one of the axles. Fig. 6 is a detail sectional view similar to that appearing in Fig. 2, showing a modification in which but a single clutch is used. Fig. 7 is an enlarged detail sectional view on line 4% of Fig. 6.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the body of our improved car preferably consists of the longitudinal side sills 1, 1, and the central longitudinal sills 2, 2, with cross sills 3.

i The platform 1 is laid upon the cross sills and is provided with side bars or side rails 5 at the edges, the said bars being arranged to rest upon the cross sills, as clearly appears from Fig. 2.

The traction wheels are secured to the axles 8 and 9, the axles being supported in suitable bearings 10 secured to the under side of the longitudinal sills 1.v The gallows frame 11 is arranged centrally of the platform or deck. The walking beam 12 is provided with handles 18 at each'end, and is centrally mounted on the gallows frame. The walking beam is connected to one of the axles through the connecting rod 14, which is connected at one end to the walking beam and at the other end to the crank shaft 15 on which is a gear 16.

A pinion 1'7 is splined to the axle 9 so that it may be shifted into and out of engagement with the gear 16, thereby throwing the hand propelling means into or out of gear as desired, the same being shown in its disconnected position in Fig. 5. A lever 18 is provided, with a fork 19 at its lower end to engage the groove 20 in the hub of the pinion 17.

e preferably secure the walking beam 12 in a horizontal position when the driving connection therefor to the axle is disconnected, so that the walking beam serves as a support for persons riding, as the car is without seats. This we accomplish in a simple manner by providing a hook 21 which is pivoted on the gallows frame.

The engine 22 is arranged in front of the gallows frame, preferably centrally of the car, as is illustrated in Fig. 2. The engine shaft 23 is provided with a fly wheel 24. The engine shaft extends each side of the engine and is providedv with a driving gear- 25 at one end and with a driving gear 26 at the other. Each of the traction wheels is secured to the axle 8 and is adapted to form one member of a clutch. Each clutch 27 is preferably provided with a flange-like periphery 28 arranged on the inside of the traction wheel and adapted to engage the inside thereof, the edge of the flange being preferably arranged to engage both the web and the tread, as clearly appears from" the drawing. These clutch members are pro vided with hubs 29 which project through the bearings 10 for the axles. At their in ner ends they are provided with annular grooves 30,- with which the forks or arms 31 of the lever 32 engage. These levers are pivoted at 33 on the bracket-like arms 34. The upper ends of the levers are connected by the links 35 and 36 to the lower end of the actuating lever" 37, Which is pivoted at 38 on the arm 39. This lever is provided with a latch 40 adapted to engage the segment ill, the latch being connected by the rod 42 to the hand piece 43 of the lever. The connection for the links 35 and 36 to the levers 32is preferably a pin and slot connection, the levers being slotted at 4a to engage the pins 45 on the levers, the object being to secure some lost motion in the connection to enable separate releasing of the clutches.

One of the clutch members 27 is provided with an external gear 46, while the other is provided with an internal gear 47 which is secured to the periphery of the clutch member. Otherwise, the clutch members are substantially duplicates. The gear 25 is arranged to mesh with the external gear 4L6, while the gear 26 is arranged to mesh with the internal gear 17. different proportions secure a different speed. It will be obvious that when the righthand clutch is actuated, the car will be driven in a direction opposite tothat in which it will be driven when the left-hand clutch is actuated, and by the variations in the proportions of the gears the variations in speed are secured.

It is sometimes of advantage in cars of this type to drive the car backward for a short distance, and it can be done by these connections without reversing the engine. The clutch connection illustrated is substantially that illustrated in our companion case filed concurrently herewith, and while it is particularly adapted. for use in this relation, other clutch means might be utilized, the main object of the invention being to provide a variable or reversing drive by a series of opposite or different traction wheels.

The clutches are held yieldingly in en gagement by the coiled springs 18 arranged on the axles so that one end engages the hub of the clutch and the other the bearing member 19. A hearing member 50 is secured to the axle, and between the members 49 and 50 we arrange bearing balls 51. These, in the structure illustrated, are shown in conventional form. The fuel reservoir 52 is preferably supported on the gallows frame between the engine and the gallows frame.

These gears being of in Figs. 6 and 7, in which but a single clutch V is made use of. WVhere it is not necessary that the car be reversed on the track, it is desirable that the same be as light as possible, and this is accomplished by the structure appearing in Fig. 6. To change the direction of this car it is lifted from the track and turned about. The structure of the clutch is illustrated at the left hand end of F 6, where an external gear is shown.

As there is only one clutch to actuate, it is done by a single lever 31, which is connected direct, as indicated in Fig. 7, in place of by intermediate link and lever. merals on the same parts are indicated in Fig. 6, the same as in Fig. 2, and the similar parts have a prime placed after the numerals. The lower end of the lever 31 terminates in the fork 31" which engages the grooved collar 30.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is: V
